West Sacramento Levee Improvements Program

Categorized Under: Environment



ICF assisted with program management counsel, environmental documentation under the National Environmental Policy Act (NEPA) and California Environmental Quality Act (CEQA), environmental permits, public outreach, and mitigation planning for a levee planning effort undertaken by the West Sacramento Area Flood Control Agency to achieve 200-year compliance for the City of West Sacramento.

Permitting will include programmatic agreements for endangered species, waters of the United States, and cultural resources. Actions under the program include rock slope protection, biotechnical bank stabilization, setback levees, seepage berms, cutoff walls, stability berms, relief wells, and adding height to the levee. A particularly challenging aspect of the supplemental authorization from a technical standpoint is the issue of woody vegetation on levees, in light of recent technical guidance and revised policy from U.S. Army Corps of Engineers (USACE) Headquarters, and the need for projects to comply. This issue has important resource and regulatory implications as vegetation under the purview of the policy is also in many cases protected as habitat under other federal and state laws in the Sacramento River system.

In addition to the program evaluation, ICF worked with engineers to evaluate early implementation projects (EIPs) which may be readied for construction in advance of or parallel with the program based on nine screening criteria. ICF assisted the USACE Sacramento District in developing the Section 408 compliance documentation through South Pacific Division and Headquarters review and approval for the EIP constructed in 2008.
